The toilet from the home's master bedroom suite fetched $2,500 at a similar auction last year. Like that one, Koltys says this auction will benefit the Sophia Foundation, a San Francisco Bay area nonprofit that aids children and families during marital separations and divorces.

"This charity auction allows me to combine my interest in protecting and helping these families and my love for Jerry Garcia's music," said Koltys, who is the foundation's chairman.
